Specification of Letters Patent.

Patented Mar. f7, 1916.

Application flied April 17, 1915. serial No. 22,068.

This invention relates to improvements in portable Sprayers, forspraying trees, plants --and fiowers, and one object of the invention isto provide a portable sprayer which is efboth for spraying plants andflowers close to theL ground `and for spraying trees or vines, etc., atany Aordinary elevation above the ground surface.

Another object of the invention is to provide a portable sprayer of thewheeled type embodying a pump for supplying compressed air to the fluidreservoir, which pump may be driven automatically in the travel of thesprayer from place to place or by hand when the sprayer is ina standingposition.

A further object of the invention is to provide a sprayer which issimple of' construction, reliable aild efficient in action, containscomparatively few parts, and which are not liable to get out of order,which may be conveniently transportedand manipulated, and

which is Ystrong and durable.V

A still4 further object of the invention Ais to provide spraying'devices, including nozzles, which will spray the fluid witha desiredforce andspread and which will be self-cleansing in action at allordinary times, but which if choked may be readily and con- A venientlycleaned.

construction, y l KLof parts herein fully described and claimed,

The invention consists of the features of combination and arrangementreference being had to the accompanying drawings in which i Figure 1 isa view in sidev elevation Vof a portable sprayer embodying my invention,showing in dotted lines a position to which the device may be tilted toraise the supporting wheel from the ground'. Fig. 2 is a top plan viewlof the Sprayer. Fig. 3 is a rear Fig. i is 'a sectional Vplan view.Fig. 5 is a transverse section on line 5-5 of Fig. 4. .'Fig. 6' is adetail view showing the construction of the connecting rod and itslatch. Fig. 7 is a view illustrat- A ing a modification. Fig. 8 is adetail view' of the nozzle. i

The apparatus comprises 'a VV-shaped frame including side bars 1integrally connected at their forward ends, as indicated at 2 andvprovided with rear handle extensions 3, a single-piece frame of theconstruction described, iliade of a rod or pipe being preferablyemployed. The sideV bars ofy the frame are provided with supporting feet3 Y at their forward ends, to support bearings i fora shaft or axle 5carrying a supporting wheel 6, on which the apparatus as a whole issupported, so that it may be trundled,

- wheel-barrow style, from place to place and suitably supported in ahorizontal position by allowing the feet 3 to come in contact Y with theground.

Suitably supported upon and fromv the frame is a horizontally extendingtank or reservoir 7 containing the fluid to be sprayed, and alsocontaining a store of air under pressure, whereby the fluid isdischarged. rlhis tank or reservoir is provided at its forward 'end witha pet-cock Sor other indicating .meanswhereby the maximum level of thefluid is gaged, allowing the operator to determine when the fluid hasreached such level in filling the reservoir, At its rear end the tank isprovided with a fluidv inlet pipe or -filling pipe 9 carrying a fillingfunnel 10 and provided .with a, controlling or cut-ofi' valve 11.

Supported pump 12, including a cylinderfand piston, f'ork Supplyingcompressed air to .the tank or reservoir. This rpump-llas its cylinderprovided withall inlet and discharge pipe or at one side of the frame isa i connection 13 at its rear end, having therein' Y a check valve 1afor permitting air Yto enter, while preventing its escape. Communicatingwith this pipe 13 and leading therefrom to the tank is an air supplypipe 15, through the pump to the tank` or reservoir, said pipe 15l'being providedv with a check valve 16 and a pressure gage 17 forobvious purposes.

The pump is adapted to be yoperated automatically or by' hand throughthe medium of the running gear of the apparatus, which includes the axle5 and supporting wheel 6. Asshown, the pump piston or plunger rod 18is-pivoted at its outer endfto a connecting rod or member 19 having atitsvforward end a'slotQO to receive and engage a crank pin 21 and acrank wheel or disk Q2 fixed to theaxle 5, and pivotally mounted on theconnecting rod or member 19 is a latch device 23Vhaving its free endprovided with which theJ compressed air is delivered from a slot 24 alsoadapted to receive and engage the crank pin 21, the slots of therod andlatch having their entrance portions arranged at an angle so as to beclosed when said elements are engaged Vwiththe crank pin, therebycoupling the piston to the crank lwheel so that in' theforward travel ofthe apparatus, the pump willbe operated-to supply compressed air. Itwill thusbevunderstood that while the apparatus yis--beingl transported`from place to placethe pump maybe automatically operatedy to replenishther'eservoir to the degree of pressure dej sired.

4The latch 23 is provided with an arm 25 which is coupled -by a suitableflexible or link connection 26 Withkthe forward end of acontrollinglever 27 fulcrumed -upon a bracket 28 and vformed or providedat'its rear end with ahandle v29 .whereby it may be moved in a verticalplane.y 1A spring 30 suitably connects the forwardlend of `the le- Vverwith kthe framework fand 4operates to vhold the same normally depressedso that thev connecting rod and latch may move Vdownwardly to engage thecrank pin and may have motion vwith the latter when con-` vnectedtherewith, .but it will be understood that by depressing the handle 29Aand vraising the forward end ofthe lever the latch y ymay bedisconnected from the [cranlnpin and y '1 with the connecting rod raisedto a'position pump out of action whenever desired.

clear of the crank disk, so as to thro-wth When .the apparatus is inuse.it may vbe tilted back to an `inclined `position Y, and supported bythe feet 32L `,and handles 3 `and the VConnecting rod* disconnected,

. whereby'the wheel 6 will be raised from the ground, allowingthe crankdisk to be rotated by means of a handle 31 to permit the "l pump to vbemanually :actuated to replenish .the reservoir V-witlrair Yduring thespraying operation. A guide'member.or-deflector 32 is provided upon theframe and overhangs the crank disk to prevent the .connecting rod from.dropping .down-behind said disk` and becomingbound in its adjustingmovel ment.

Arranged at the sides' of i extending .outwardly therefrom are vbracketsor outriggers 33 which support theouter end ofspray pipes 34communicating at their vinner ends with the reservoir through ya.connection 35, Vwhich connection is provided with a controlling valve36.j.adapted to lbe operated by a rearwardly extending controlling rodorf shaft 37, allowing the operator .Y also control the discharge of thefluid. The

Y spray pipes carry nozzles 38 ,each comprisf. Ving a :bo'dyvportion 39provided at itsouter end vwith a chamber 40 and a seat 4lvfor a sprayvalve i42 disposed within saidY cham whiletrundling the device .lforspraying rows :of growing :vegetation or plants to `the iframe and berand having fixed to the outer side there-V of'rone endof Va coiledseating spring agitator 43.4'l'llhey outerhend of the body 39 is.-

v4,internally threaded to .receive a cap' or V,tip-

44 provided with an outlety 45 through which the fluid is sprayed, agasket46 being interposed between said cap and the outeredgeV ofthe bodyto maintain a fluidtight joint. The fluid forced outwardly un- A der adetermined air pressure from the reservoir acts upon the valve Vordisk42 to force it outward to the Alimit aifordedbyv` .thec'ompression ofthe spring43, which is of sufficient strength to ordinarilyholdthej` Ydisk substantially seated. As. shown, the disk is .provided with.a-spiral groove .47

"through which the fluid finds its way, the

fluid passing into the chamber 40 andfbetween the coils ofthespr-ing.andbeingthereby atomized and discharged in the form Vof Y a finespray through'the'outlet 45, bywhich Y Y a' spray o f the Vdesireddegree'bfliineness y yand area is produced. A rear; discharge .pipe

48 is also provided,YA and this pipe may be 5- vwhollyv or partly of..an .elastic nature,` .and

it is adaptedwto ,be coupled to an extension .pipe 49 provided with .anozzle 50- ofV the construction described. This extension may be .of anysuitable length andis designed particularly ffor use inoverheadspraying,

so that elevated vines orllimbsof .trees may be readily and convenientlysprayed.

Insteadof mounting the reservoirs upon f a frame of thewheel-barrowtype, theparts of the. apparatus may bemounte'd yupon any other vehicle`running gear, such as that of the wagon type and' which -includesfrontand rear axles-and wheels.
